ecg pulse deficit biventricular bigeminy

 

Answer : Most probably  B .

What we feel in peripheral pulse ,  is one weak and the one strong beat in sequence .The later is due to post VPD potentiation. Since there is a compensatory pause , ECG rate (Number of QRS complexes /mt)  and pulse rate are same .

Ironically , heart rate and ECG rate are not same as VPDs impact mitral valve more than aortic valve  and cause additional  S 1 than S 2 making heart rate considerably more than pulse rate and logically it must be  double the pulse rate . This may be difficult to  appreciate by auscultation, but can be documented by phono-cardiogram or by M mode echocardiogram.
